A scientist has discovered a new species and is tasked with identifying which of the kingdoms of life the organism might fit.
Multicellular with nuclei
Presence of a cell wall containing chitin
Heterotrophic
Non-motile
Question options:
Fungi
Protista
Plantae
Animalia
Protists are a group of organisms that are eukaryotic. However, they are a diverse group, with some of the members of the group having a more recent common ancestor with plants while others have a more recent common ancestor with animals. Algae are protists that are more closely related to plants than any other group.
Which characteristics would algae share with plants but NOT with animals?
Question options:
DNA
Ribosomes
Chloroplasts
Mitochondria
Using the provided images, classify these 2 organisms (animal, plant, bacteria, protist)
The Study of Life discusses themes in biology, how life is organized, the types of cellular life forms, evolution, and the process of scientific thinking. In this post, you will demonstrate an understanding of you've learned about the themes in biology, how life is organized, the types of cellular life forms, evolution, and the process of scientific thinking. Choose one concept and describe your understanding of the concept, add information to that concept and lastly pose a question to the class so that they can get involved.

- The three domains of life are Bacteria, Archaea, and Eukarya. Which of the following statements best represents a significant difference between these domains? All domains have membrane-bound organelles and a nucleus. Eukarya have membrane-bound organelles and a nucleus, whereas Bacteria and Archaea do not. Bacteria and Archaea have membrane-bound organelles and a nucleus, whereas Eukarya do not. None of the domains have membrane-bound organelles and a nucleus.arrow_forwardChoose one prokaryote (bacteria or archaea) AND one protest. You can choose a species or more general taxonomic group of interest. Then address the following questions for each. 1. What does the organism look like? Describe or include an image. 2. How does it obtain energy? 3. How does it reproduce? 4. What are its close relatives in the tree of life? 5.

- WHICH ORGANISM CAN MOST LIKELY BE CLASSIFIED IN THE DOMAIN BACTERIA? Required to answer. Multiple choice. A predatory organism that depends on hunting plant eaters for food a multicellular organism that reproduces via sores and gets food from a dead log a photosynthetic organism that undergoes sexual reproduction and produces seeds in a cone A unicellular organism that has a simple structure and is commonly found in the intestinesarrow_forwardENDOSYMBIOTIC THEORY is the evolution theory that includes a larger and one smaller cell. The larger cell act as a host and the smaller cell is called the endosymbiont that is engulfed by the host cell. The larger cell referred to eukaryotic cell and the smaller cell represent prokaryotic cell. While BIOCHEMISTRY, is the study of the chemistry of cells and organisms. Thus, it is concerned with the types of molecules found in biological systems, their structure, and their chemical properties.
